Abstract
A system and associated method deliver a respiration therapy. Stimulation pulses are delivered to activate a right portion of a patient's diaphragm and to activate a left portion of a patient's diaphragm. A control processor determines dyssynchrony of a respiratory response to the stimulation pulses and adjusts a stimulation control parameter controlling the delivering of the stimulation pulses in response to dyssynchrony of the respiratory response.
Claims24
A method for delivering a respiration therapy, comprising:
- delivering a first plurality of stimulation pulses to activate a right portion of a patient's diaphragm and a second plurality of stimulation pulses to activate a left portion of a patient's diaphragm;
- determining dyssynchrony in a respiratory response to the first plurality and the second plurality of stimulation pulses;
- and
- adjusting a stimulation control parameter controlling the delivering of the first plurality of stimulation pulses and the second plurality of stimulation pulses in response to the dyssynchrony.
A respiration therapy delivery system, comprising:
- a plurality of electrodes for delivering a first plurality of stimulation pulses to activate a right portion of a patient's diaphragm and a second plurality of stimulation pulses to activate a left portion of a patient's diaphragm;
- a pulse generator coupled to the plurality of electrodes;
- a sensing unit to generate a signal correlated to a respiratory response to the first plurality of stimulation pulses and the second plurality of stimulation pulses;
- a control processor configured to determine dyssynchrony in a respiratory response to the first plurality and the second plurality of stimulation pulses and adjust a stimulation control parameter controlling the delivering of the first plurality of stimulation pulses and the second plurality of stimulation pulses in response to the dyssynchrony.
A computer-readable medium storing a set of instructions which cause a medical device system to perform a method, the method comprising:
- delivering a first plurality of stimulation pulses to activate a right portion of a patient's diaphragm and a second plurality of stimulation pulses to activate a left portion of a patient's diaphragm;
- determining dyssynchrony in a respiratory response to the first plurality and the second plurality of stimulation pulses;
- and
- adjusting a stimulation control parameter controlling the delivering of the first plurality of stimulation pulses and the second plurality of stimulation pulses in response to the dyssynchrony.
